Audacity: A Digital Audio Editor

*******************************************************************//**
\class AdornedRulerPanel
\brief This is an Audacity Specific ruler panel which additionally
has border, selection markers, play marker.
Once TrackPanel uses wxSizers, we will derive it from some
wxWindow and the GetSize and SetSize functions
will then be wxWidgets functions instead.
